t can switch between three types of Exposure control modes by manipulating EXP switch (Exposure control switch)
on the rear panel.
①
Line period exposure
(at scan rate 7.54kHz or less) EXP setting N=0
Exposure during each period of EXT SYNC
② Fixed time exposure
(at scan rate 3.7kHz or less) EXP setting N=1 to E
Exposure during the period of the equation below
from the timing of leading edge of EXT SYNC
Exposure time= 25.6 × N + 40 clk
(μsec )
③
Pulse width exposure
(at scan rate 3.7kHz or less) EXP setting N=1 to F
Exposure during the period o f the pulse width of EXT SYNC
Exposure time = H period of SYNC + 40 clk
– 6clk
